Question

The area, A, of the rectangle below is 3/4 square ft. If A = length x width, what is the length of the rectangle?

Answer 1

`(3)/(4w) =l`

Explanation:

The area of a rectangle is found using the formula A = l*w. We know the area is A = 3/4 square foot. To find the length in terms of w, solve for l by multiplying by the reciprocal of w.

`A = l*w\\(3)/(4) =l*w\\(3)/(4) *(1)/(w) = l\\(3)/(4w) =l`
